PIPE-ORG/-UNL SPECIFICATION forming part of Letters Patent No. 273,369, dated Mai-C11 o, lesa.

Application ined Juiy 3i, 188e. (Merisi.)

To all whom it may concern.-

,Be it known that I, THoMAs H. KNoLLIN, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Pipe-Organ Valves. of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention consists, iirst, in the combination of a wind-chest provided with longitudinal partitions and with ports through its top intermediately between said partitions at varying distances therefrom, and wind-sockets situated in the wind-cliest and connected with said ports.

The invention also consists in a novel, simple, and effective means for adjustably securing to the wind-chest the valve b v which the ingress of air to the aforesaid socket is controlled, all as hereinafter more fully described, and specifically set forth in the claims.

The invention is fully illustrated in the annexed drawings, wherein Figure 1 is a transverse section through two of the passages of the wind-chest provided with niy improvements. Fig. 2 is an inverted plan view, illustrating the means of connecting the valves with the wind-chest. Fig. 3 is an enlarged detail view of the connection of the valve and its actuatiiig-rod5 and Fig. 4 is a plan view, on a reduced scale, ofla section of a wind-chest provided with niy invention.

Similar letters of reference indicate corresponding parts.

A represents the wind-chest or air-chamber of a pipe-orgaii, of any ordinary or desired style, said wind-chest being provided with a series of parallel partitions, forming longitudinal channels, which are charged with wind from a bellows or suitable blower. rIlhe aforesaid wind-chaiinels I tap at or near their center by holes bored vertically through ythe top plate of the wind-chest, the organ-pipes P being mounted on the wind-chest and having their tapered base ttcd into the aforesaid holes. Inside of the wind-chest A, and intermediately between the partitions thereof, I place a series of sockets, a, one for each pipe, said sockets being separate and independent of the partitions, and consisting of ports arranged in the several channels of the windchest directly under the holes bored through the top board and framed or boxed into the top and bottom boards, so as to tit air-tight therewith, said ports having internally a vertical channel, which is closed near the bottom, and has its upper end open and in range with the holes in the top board, and thus in direct communication with the pipes. It will bepobserved that the aforesaid communication between the socket a and organ-pipe P is of the simplest and cheapest construction, and offers less resistance to the passage of the windthan any device hitherto employed -in pipeorgans. The described socket communicates with the windchest by a port or horizontal channel, 71, bored into the side of the socket and intersecting the vertical channel thereof some distance from the bottom, so as to form at the base of the socket a dead-air space for the collection of the dust which may enter the socket through the pipe P.

By the before-described ein ploynient of the extra pockets a between the partitions of thc wind-chest, I obtain greater range for the adjustment in the location of the pipes on top of the wind-chest than is afforded by thelocation of the sockets in the partitions as heretofore constructed, inasmuch as the sockets can be placed at different points in the width of the channel to accommodate different-sized pipes over them, and can also be turned to bring` their val ves or air-inlet ports in range with actuating-rods running` diagonally or obliquely across the under side of the wind-chest, which latter arrangement is frequently desired.

The bottom board of the windchest A is provided with an aperture,f, in range with the side of the socket a which has the aforesaid horizontal channel or port. Through this aperture f is extended the shank or arm d ot' a clack-valve, c, which is formed in one pit-cc with said shank and fitted over the port ofthe socket a, and hinged or flexibly connected to a collar or plate, g, which is secured to the under side of the wind-chest, said plate beingprovided with a central aperture, p, and has secured to its side adjacent to the wind-chest a leather or other flexible air-tight disk, t, through which the shank d ot' the valve passes, and to which it is connected air-tight by gluing the edges of the pierced portion ofthe disk onto the said IOO purpose. rllie plate g and the valve c, conshank d, thus rendering the action of the Valve perfectly noiseless. rlfhe diskt' is so stretched across the plate or collar g as to prevent as lnucli as possible a reciprocating or longitudinal movement ot' the valve c, which is designed only t'or a tree oscilla-ting motion in the openings iii the collar g and bottom of the windchest, which openings are amply large for the nected thereto, are rendered detachable and adjustable in their position by means ot' eyescrews K K, inserted in the bottom ofthe windchest in proximity toy the edge ot' the plate g, and engaging with their eyes the under side of said plate. Byturning said screws so as to bring their eyes on a tangent to or parallel with the edge of the plate the latter becomes liberated, and can be removed together with the valve hinged thereon, as before described. The edges ot' the plate g are beveled so as to canse the eyes ot' the screws K K to ciowd the plate away from them. Hence by turning the screws K K at one edge ot' the plate g. so as to carry the plane ofthe eye of said screws from a radial toward a tangential position in relation to the plate y, and then turning the screws on the opposite edge of said plate so as bring the plane ot' their' eye to stand nearer in a radial position to the plate g, the, eyes ot' the latter screws crowd the plate g laterally into the desired position without necessitating the removal ofthe screws, as is the case with common screw-fastenings.

I do not claim the employment of the described eye screws simply for attaching the plates g, as l am fully aware that the mere substitution ofone attaching-screw for another does not constitute invention; but it is thepeculiar arrangement and adaptation of a particular form of screw-head, which by a mere partial turn is capable ot' shifting the plate on which the valve is hinged. This arrangement at't'ords a very simple, convenient, and eli'ective means ofl adjusting` the valve in relation tothe port ofthe socket, a.

Thevalve of one channel of the wiiid-cliest is connected with the valve ot' the adjacentchan` nel by a rod, Z, extended along` the under side ofthe wind-chestanii connected with the sha n ks d ot' the respective valves. One end ot' the rod Z is connected to a bell-craiik or elbow lever, s, which is actuated by the keys ot' the organ in any of the well-known manners. The opposite end ot' the rod l is connected with a springrod, t, which draws said rod in that direction and normally' holds the valves in a closed position. It is suspended t'roin a set-screw, u, applied to the exterior of the wind-chest. lts suspended portion is strained over a t'ulcruin, c, in the form of a block secured to the extewhat* rior ot the wind-chest beneath the set screw u. By forcing the said screw more or less into the wiiid-chest the strain of the spring-rod over the tulcrum e is increased or diminished, and thus the draft on the rod l may be regulated. [n order to facilitate the connection and disconnection ot' the valve, l connect the rod l with the shank d ot' the valve by means of an eye pin or staple, m, inserted into the end ot the shank d longitudinally thereof, so as to allow it to be readily withdrawn therefrom when desired. The rod Z passes through the. eye ot' said pin or staple, and is confined in its position in the said eye by means ot' nuts n n, applied to the rod at opposite sides ot' the staple m, telt or cloth washers being` interposed between the staple or nuts to render the action noiseless. The rod Z, l render adjustable in length and removable in parts by forming it ot' sections, whcli I couple together by a duplex nut., t, in the form ot4 a leather disk provided with a separate eye for each ot" the sections to be coupled.

A valve similar to but proportionately larger than that hereinbefore d escribed may bea pplied to the wiiid-chest at the mouth or air-inlet thereof, and connected with the register or stop-knob, thereby rendering the action ofthe latter very easy and entirely t'ree from liability ot' becoming bound and hard to draw. Also, a crescendo-pedal can be arranged very simply with this plan ot' the valve.

Havingdescribedmyinventioinwliatclaiin, and desire to secure by Letters Patent, is-

l. The combination ot' the wind-chest A, provided with longitudii'ial partitionsand with ports through its top intermediately between said partitions at varying distances therefrom, and the sockets c, situated in the wind chest and connected with said ports, substantially ioo in the manner shown and described.

2. In combination with the windcliest A, provided with the aperture f, socket a., and valve c, the collar g, applied to the under side ot' the wind'chest and having connected to it IOS the valve, and theeye-screws K K, inserted in the windchest outside of the collar g, and hearing with their eyes against the edges ot' the saine, and serving to shit't the said collar and adjust the valve to the port of the socket, 110

substantially as specified and shown.

In testimony whereot'l have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of' Onondaga, in the State ot'New York, 115
